HINGED SPRING-WIRE MATTRESS.

Specification of Letters Patent.

Patented Jan. 30, 1917.

Application filed October 19, 1915. Serial No. 56,678.

1 0 all to hom it may concern Be it known that 1, DAVID KUrnnMAN, a citizen of the United States, residing at 180 East Houston street, New York, county of New York, and State of New York, have invented certain new and useful Improvements in Hinged Springire Mattresses, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of this invention is to furnish a convenient means of hinging one edge of a. spring-wire mattress to the frame of a bedstead so that the mattress can be tipped up to facilitate the cleaning of the floor beneath the bed. By suitably hinging the edge of the mattress, it may be readily tipped up and remain in an erect position during the sweeping or scrubbing of the floor. In such constructions, it has been common to provide the frame of the spring mattress with special hinged members to operate in connection with corresponding members upon the side-bar of the bedstead,

construction any modification of or attachment to the frame of the spring mattress is avoided, by utilizing the brackets at the corners of the spring mattress-frame as hinged members for jointing to the side-bar of the bedstead.

The corner brackets in the present invention have fiat flanges which project transversely at both ends of the spring-mattressframe, and such flanges are converted into hinges by merely perforating them to admit a hinge-pin, and mounting forked bearings upon the side-bar of the bedstead to receive the flanges, which are jointed thereto by extending a pin or bolt through both. Such hinging of the two frames together is eflected at one side only of the bedstead, and permits the opposite edge of the spring mattress to be raised to a vertical position, in which the forked bearing supports it while cleaning beneath the bed.

The invention will be understood by reference to the annexed drawing, in which- Figure 1 is a side-view of the bedstead and spring mattress, both being broken away at the middle of the length to shorten the view; Fig. 2 is across section on line 2-2 in Fig. 1 looking in the direction of the arrow marked 2; Fig. 3 is an end view of one of the corner brackets, side views of which are shown in Fig. 1; Fig. 4 is an end view of one of the forked bearings; and Fig.

5 is a perspective view of one of said bearings. Fig. 6 is an end view of the hinged connection of the wire mattress with the bedstead, the mattress being tipped upwardly.

a, a designate the head and foot of the bedstead, which are connected by tie-bars Z).

(Z is the wire of the spring mattress stretched between end-bars d, which are extended transversely between the upwardly projecting arms 0 of the corner brackets. The body of the spring wire is omitted in Fig. 2, and only the tension-springs c are shown, by which the mattress wire is commonly held under tension. These brackets are formed with sockets e for the side-bars or braces e, which with the brackets and end-bars 03 form a square frame on which the spring wire (5 is stretched. The heads or tops of the brackets are connected to the sockets e by flat flanges f at right-angles to the sockets, which flanges by forming boltholes 9 therein operate directly as hingemembers for the wire mattress-frame. The flanges are made with a vertical outer edge even with the outer edge of the spring wire mattress, and with a horizontal edge at the bottom which is adapted, at one side of the bed, to rest upon the angle tie-bar b, as is shown in Fig. 6.

Corresponding hinge-members or bearings are fitted to one of the tie-bars b of the bedstead, which are commonly made of angleiron as shown in Fig. 2. Each bearing in such case made with an angle-shaped footpiece it to fit the top and outer side of the tie-bar b, and with a hook it to fit the inner edge of such tie-bar.

Two bearing-plates 71 project upwardly from the foot-piece at a suitable distance apart to admit the flange f, and each bearing-plate is perforated with a bolt-hole g which, with the bolt-hole 9, receives a hingebolt. The foot-piece of such angle-bearings can, by tipping it, be applied to an angleiron like the tie-bar b, and is thus a removable attachment which can be applied orremoved at pleasure, and tenings, as the hook holds the bearing firmly in place when the weight of the mattress rests upon it.

To support the spring mattress when tipped upwardly as shown by dotted lines in Fig. 2, the bolt-hole g is made in the lower corner of the flange 7 at one side of the socket, at the same distance from the outer which needs no fas-' edge of the bracket as the bolt-hole g is located above the top side of the foot-piece it, and when the mattress is swung upwardly the outer edge of the bracket becomes horizontal and contacts with the foot-piece, and

supports the wire mattress in an erect position. Such contact is secured by locating the hole 9 at one side of the socket, as described.

Fig. 2 represents the wire mattress in full lines in its normal position, being hinged at the right-hand side to one bedstead tie-bar b, and at the left-hand side having the lower edge of the flange f resting directly upon the other tie-bar b.

Fig. 6 shows the hinged connection of the mattress with the tie-bar Z), upon a larger scale than Fig. 2, and the mattress tipped upwardly and supported by the contact of the flange 7 with the foot-piece it.

Many springmattresses are in use with corner brackets of the shape shown in the drawing, and can be readily hinged to the side-frame of the bedstead by merely forming the hole 9 in such bracket flanges, and applying the hinged bearings to the side-bar of the bedstead.

Gopies of this patent may be obtained for five cents each, by addressing the The making of any separate hinge-part for the. spring mattress-frame is thus avoided,' and-a hinged connection between the spring mattress-frame and the bedstead is secured at the smallest possible expense.

Having thus set forth the nature of the invention what is claimed herein is:

The combination, with a spring wiremattress having corner brackets connected by side-bars, and each bracket being formed with a socket for the side-bar and a flat flange transverse thereto and projected at one side of the socket and the flange having a bolt-hole in its lower corner at one side of the socket, of bearings pivoted to the boltholes in said flanges and having each a footpiece adapted to detachably engage the tiebar of the bedstead, and the outer edge of the flange being adapted to rest upon the foot-piece and maintain the mattress in a vertical position when the mattress is tipped upwardly, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand.
